High-quality, high performance, and high reliability – the Sunmodule Plus® is designed and built for long-term yield stability and ease of use.

Every module is factory flashed at standard test conditions (STC) to determine the power output and then sorted in 5 watt increments. Only modules with a flashed power that is greater than or equal to the nameplate rated power are delivered. Flash report data is provided with every order.

The proven design of the patented low profile Sunbox junction box, has been installed on over 4,000,000 modules. Integrated by-pass diodes and sealed welded connections ensure reliability and eliminate failures resulting from exposure to the elements. The molded fins on the exterior housing dissipate heat quickly to ensure high reliability and long life.

The patented box channel frame design provides extraordinary stiffness in bending and torsion. The laminate with 4 mm glass is set deep in the frame channel and secured with precision applied adhesive. The frame is assembled by press fit to maximize strength and longevity. The result is an extremely robust package that can be mounted in any orientation and can withstand static loads of up to 113 psf.

SolarWorld is committed to manufacturing in the United States and makes use of the superior automation technology and employee productivity available here. SolarWorld promotes local economies and energy independence. While many products claiming to be "made in the USA" are merely assembled from imported components, SolarWorld makes Sunmodules entirely in the USA from American-made raw materials and components.

Plus-sorting guarantees the highest system efficiency. Only modules that achieve the designated nominal performance or greater in performance tests are dispatched. These SolarWorld modules have received top marks in numerous independent performance tests: In Photon test laboratory's endurance test, Solarworld's modules occupied first place in 2008 and in 2009 and were assessed by the OKO-TEST consumer magazine as "very good."

25 Years Linear Performance Guarantee

SolarWorld guarantees a maximum degeneration in performance of 0.7% p.a. for more than 25 years - a clear additional benefit compared with the conventional two-stage industry guarantees. In addition there is a product workmanship warranty that covers 5 years.

Industry leader

As the largest solar PV manufacturer in the United States since 1977, SolarWorld has the technology and market experience to bring you the best possible PV system.

-Vertically integrated from raw silcon to modules, kits, and systems.

-Developed the first grid-connected PV systems in the world.

-The first to offer UL-listed modules.

-The first to offer a 25-year warranty.

-Established the SolarMaterials recycling subsidiary in 2001 and was the first to recycle whole obsolete modules.

100 percent PV

SolarWorld is dedicated exclusively to the business of solar energy and combines all stages of the solar photovoltaic (PV) value chain from raw silicon to solar wafers and cells to modules, kits and turn-key solar power plants. SolarWorld is making PV a mainstream energy choice throughout the Americas by continually improving performance while lowering equipment and installation costs for both on and off-grid applications.

30 years of experience

After 30 years of experience our systems have proven durability. With the acquisition of Shell Solar's crystalline business in 2006, SolarWorld brought onboard three decades of solar history in America. Previously known as ARCO Solar and Siemens Solar, SolarWorld's Camarillo, California factory was one of the first solar PV companies in the world. SolarWorld has since more than tripled the capacity of this facility and opened North America's largest wafer and cell factory in Hillsboro, Oregon.

Help for underdeveloped nations

SolarWorld's non-profit arm, Solar2World, brings the benefits of clean sustainable solar energy to underdeveloped areas around the world. Solar2World has already helped villagers in China and Africa gain access to electricity, and the economic and social benefits it brings. Projects in Latin America are underway now.
